Abstract

Apparatus for pumping a pulp suspension and simultaneous abduction of gas from the suspension is disclosed. The apparatus comprises at least one pulp pump including a pump housing with an inlet, a first outlet for the suspension, and a second outlet for the gas. The gas outlet is connected to at least one external vacuum pump by a gas conduit including a substantially vertical portion having a maximum height, located on a level above the pulp pump, and a flushing water supply for the supply of flushing water to the gas conduit connected above the substantially vertical portion of the gas conduit.
